An apparatus for targeting a desired target site on a body tissue that separates a first body cavity from a second body cavity of a patient includes a catheter having a longitudinally extending catheter lumen and adapted to provide access to the first body cavity. A framing member has a collapsed condition in which the framing member is adapted for insertion into the first body cavity through the catheter lumen and an expanded condition in which the framing member is adapted for placement within the first body cavity. The framing member has a framing member body. At least one target point is carried by the framing member and is adapted for placement adjacent the desired target site. At least one target wire is attached to at least one target point. At least a portion of the target wire extends through the catheter lumen. The target wire is substantially spaced apart from the framing member body. A method of using the apparatus is also described.
